This; invention. relates to a converter such as may be used for the converting of coppermatter into pure copper by achemical union of; the impurities; as iron with, the, silicious lining or other material: in. the converter.

The, objectis; to provide a; converter; w c as! peculia va tag sult n from the manner of articulating its several: parts; and: in, thepeculiar-shape of some of e e par s. so. a o locat the. ar i at on of; the, top peculiarly with reference to the upporting.

Referringtothe drawings,Figure 1 is an end elevation; and Fig. 2 is a side elevation of the converter.

The shell 1 is irregularly cylindrical in cross section, that is, all. its longitudinal elements are parallel to each other and do not intersect a right angularly transverse plane in a circle. To be more specific, the irregularly cylindrical shape is brought about by bulging the shell into ridges 2, 3, at its lower front and back edges. At its upper front and back portions the shell eX- tends upwardly into tangential converging planes 4, 5. These ridges are made of cast steel sections 6, 7, and the tangential edges of the shell 1 are reinforced by steel castings 8, 9. To this irregularly cylindrical shell 1 is secured cast steel heads 10, 11, of frusto conical shape, for the most part reinforced by ribs 101, 111. The inner edges of the heads 10, 11, are shaped irregularly cylindrical to correspond with the edges of the shell 1 to which they are riveted. Treads 112, 112, are formed upon the heads 10, 11, for coaction with supporting wheels 12, 13, mounted in some suitable Way not shown. One set of these wheels 12, is suitably grooved to prevent displacement in coacting with one of the treads 112.

The shell 1 is open at the top and the treads 112, 112, are mounted upon the tapered portion of the heads 10, 11, and

formed lugs 61, 71, 81, 91. These lugs are conveniently bored for the purpose of taking hold of the converter by means of a crane or other lifting device, either to rotate the same or bodily transport the converter from one lace to another. The lower lugs, 61, 71 ave their lower edges in a coincident plane for the purpose of roviding means for stable resting on a flat 'oundation when the converter is off its support allowing the rotation thereof. The top 15 is ordinarily formed of cast steel and made in two pieces, as shown, or made in one or more pieces. It also has attaching lugs 153. Part of the body of the shell is formed of plate steel, while the upper edges and the ridged ortions are formed of cast steel, as hereinbefore stated. From the above descri tion of the inven tion it will be apparent t at when this converter is to be relined, which, as is well known, necessitates removal of the top 15, and upon such removal of the top 15 the converter will present a plane edge which is entirely free from intersection with the adjacent treads, and which lies in a lane which may be tangent to these trea s, as shown, or which may lie entirely without re t such ie-met r as; no o. e t'er v of" t ides; s

the treads. The essential feature is to present such a plane surface or edge which will be free from interference with the treads. This being the case, a platform may be built at the level of this plane edge and the lining material may be brought to the converter upon this platform without any interference with projecting treads, as was heretofore the case.

By extending the converter shell upwardly in the way described, to a plane tangent to or above the treads, the line of articulation of the top and remainder of the converter is sufiiciently removed from the zone of intense heat of the converter so that burning out at this lace of union is prevented. By bulging t e converter shell at the lower front and rear sides, additional space is provided within the converter for lining material so that additional thickness of lining is possible at points immediately below the level of the twyer on either side of the converter, that is, both adjacent the twyers and directly opposite them and about in line with the blast. At these points the lining is especially subject to erosive and chemical action, and by so bulging the shell into ridges at these points, more lining material is possible for the necessary chemical reaction during the process of converting. This bulging of the shell also lowers the center of gravity and makes the turning moment less than in the converters of the prior art. It should be especially noted that the heads are integral or one-piece parts and have no joints except those with the shell 1 and the top 15.

It should be understood that it is not desired to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art. I

It is claimed and desired to secure by Letters Patent,

1. In a converter the combination of a cylindrical drum, an end on said drum pro vided with a continuous tread to )ermit complete inversion of the converter, t e tread being of a diameter at least e ual to the smallest diameter of said cylinder, riction wheels coacting with the tread for supporting the converter, and a top secured to the drum in a plane free from intersection with the tread.

2. In a converter the combination of a cylindrical drum having treads, wheels coacting with the treads, and a top secured to the drum at a joint lying wholly between the treads and in a single plane.

3. In a converter, a shell of irregular cylindrical section having projecting ridges at two portions of its curvature and a plurality of twyers adjacent one of said ridges and directing the blast into the converter toward the other of said ridges.

4. In a converter, a shell of irregular cylindrical section having projecting ridges at two portions of its curvature and lugs provided at the projecting ridges all combining to provide for stable resting on a plane foundation.

In testimony whereof, I afiix my signature in the presence of two witnesses.
